Logic

Whilst not directly related to shell programming, understanding of basic logic operations – AND, OR, NOR, XOR, NAND, etc, are as important to shell programmers as to C, Java, .Net and other coders.

My recent interactive logic gate page seems to have become quite popular; it’s just a simple implementation of each of the major logic circuits in use. If you want to see more, say so – I’ll add anything you ask for ;-)
